Video texture on blender cube displayed all over the cube, not separately on each faces while using it in unity
Well, as i assume many noobs like me will possibly meet the joys of playing with UVs and so will they struggle with this aswell, here is the proper way to achieve this (as i said, i missed something about UVs):

In order to make sure each face is treated as an unique surface, go to blender, switch into edit mode and repeat this process for each and every single face of your cube/object:


Select your face or the ones wich are part of it
Ctrl + E -> make seam
Press "U" -> Unwrap
If you've done that right, the UV editor should show you only the shape of what you've selected.
Redo for the next face until you've done that for each one of them.


Worked for me, spent hours wondering "How" Hopefully that will help peoples out.
